A chronology of the highs and lows during the three-year Tommy Tuberville era at Texas Tech:

■ Jan. 9, 2010: Tommy Tuberville is hired as the 14th head football coach at Texas Tech. He replaced Mike Leach, who was fired shortly before the Alamo Bowl the previous December due to allegations of players mistreatment and insubordination. Tuberville took the position at a time when the Tech fan base was extremely fractured because of the Leach firing.

■ Dec, 4, 2010: Tuberville denies rumors that he is interested in or has talked with the University of Miami regarding its head coaching position, which opened after Randy Shannon was fired the previous month. Tuberville was an assistant at Miami from 1986 to 1993, but said in regard to the speculation, “I’m happy to be here. We just got this thing started.”

■ Dec. 23, 2010: Texas Tech announces that defensive coordinator James Willis is leaving the program “to pursue other career opportunities” after just one season with the Red Raiders. It was later discovered that Willis had talked to the University of Florida about an open position, and that Tech found out through a third party. Both the university and Willis agreed it would be best if he left. Later, it was revealed Willis was involved in a domestic dispute at a residence in Wolfforth prior to him leaving, but Tech insisted it was not a factor in his departure.

■ Jan. 1, 2011: Texas Tech defeats Northwestern 45-38 in the Ticket City Bowl at the Cotton Bowl in Dallas, making Tuberville the first Tech coach to win a bowl game in his first season since DeWitt Weaver’s 1951 team beat Pacific 25-14 in the Sun Bowl. It would be the only bowl win for Tuberville with the Red Raiders.

■ Jan. 18, 2011: Tuberville received a one-year contract extension through 2015, increasing his base salary to $300,000 per year. It also set his guaranteed outside income at $1.7 million for the 2011-12 school year, with increases of $100,000 per year to $2.1 million for 2015-16.

■ Jan. 21, 2011: Tech hires 39-year-old TCU safeties coach Chad Glasgow as the new defensive coordinator. Glasgow brings a fiery, high-energy presence to the practice fields and sidelines. He replaces James Willis, becoming Tech’s third defensive coordinator in as many years.

■ Oct. 22, 2011: Tech shocks the Big 12, and the rest of college football, by racing out to a big lead and holding on for a 41-38 victory at Oklahoma to improve to 5-2 on the season. The Sooners were ranked No. 3 in The Associated Press Top 25 and No. 1 in the coaches’ poll. It is one of the biggest upsets in college football that season and is Tuberville’s fourth career win over a Top 5 team.

■ Nov. 1, 2011: Suzanne Tuberville, the wife of Tommy Tuberville, is involved in a traffic accident with two elderly people. According to reports, Suzanne Tuberville ran a red light at the intersection and hit the car driven by Nelda Purdy as it turned on to Slide Road from 57th Street. Ira Purdy, 87, a passenger in the car, suffered a head injury, broken leg and broken ribs, and died four months later. As of February, the investigation was still ongoing and no charges had been filed.

■ Nov. 12, 2011: Texas Tech is humiliated in front of a home crowd as Oklahoma State routs the Red Raiders 66-6 at Jones AT&T Stadium. The 66 points is a record for most points allowed in a single game by a Tech team. Two weeks later, Baylor hung the same number on Tech, winning 66-42 and capping a season-ending five-game losing streak for the Red Raiders. Tech didn’t win another game after upsetting Oklahoma, finishing 5-7 and posting its first losing season since 1992.

■ Dec. 29, 2011: Tech and defensive coordinator Chad Glasgow reach a separation agreement after a bizarre 10-day chain of events. Rumblings began when junior-college defensive back Kass Everett initially announced plans to sign with Tech on Dec. 21 but four hours later faxed his paperwork to Oklahoma, claiming he couldn’t reach Glasgow because Glasgow’s cell phone had been disconnected. E-mails later obtained by the Avalanche-Journal show that in a letter dated Dec. 22 from athletic director Kirby Hocutt, Glasgow told Hocutt he had cleaned out his office and was resigning as defensive coordinator, which he also expressed to other Tech officials. But Glasgow insisted he was still the defensive coordinator as of Dec. 23 and asserts via e-mails the next several days that he is still on staff. An agreement was reached on Dec. 29 for Glasgow’s departure. Under Glasgow, Tech’s defense ranked last in the nation (120 teams) in rushing defense, 113th in pass efficiency defense, 115th in total defense and 117th in scoring defense.

■ Jan. 9, 2012: Tuberville hires Art Kaufman as Tech’s fourth defensive coordinator in four years. Kaufman, 54, had been on the North Carolina staff for three seasons, and had been Tuberville’s defensive coordinator at Mississippi.

■ Feb. 24, 2012: Seven people file a lawsuit in Alabama, claiming John David Stroud and his business partner, Tommy Tuberville, bilked customers of their investment firm out of about $1.7 million. Tuberville was a managing partner of the firm when he coached at Auburn. He denies any wrongdoing and, a month later, seeks dismissal of the case against him.

■ May 7, 2012: Tuberville is not charged in a 21-count criminal indictment against former business partner John David Stroud. However, he could still face a civil lawsuit by the seven plaintiffs who claimed they were defrauded out of about $1.7 million in investments.

■ Oct. 13, 2012: Tuberville earns his fifth career win against a Top 5 team as the Red Raiders stun a potent West Virginia team in a 49-14 shocker at Jones AT&T Stadium. The Red Raiders rack up 676 yards against former assistant coach Dana Holgorsen and hold then-Heisman Trophy candidate Geno Smith to 275 passing yards and one touchdown.

■ Oct. 20, 2012: The Red Raiders exact a measure of revenge against Glasgow, who returned to TCU as safeties coach, by winning a 56-53 triple-overtime thriller over the Horned Frogs at Amon G. Carter Stadium. Just like the previous year, however, the Red Raiders would slide to a finish, losing four of their last five and allowing the grumbling from the fans to grow louder.

■ Nov. 10, 2012: The Red Raiders struggle to get past lowly Kansas, winning in overtime 41-34 at Jones AT&T Stadium. But no one really wanted to talk about the game, but what happened during the game. In the third quarter, Tuberville is seen on national television angrily reacting to personnel confusion on the sidelines, and appears to take a swipe at graduate assistant coach Kevin Oliver, yanking Oliver’s headset and cap off his head in a violent motion before berating him for several seconds. Tuberville initially dismisses the incident, saying he was trying to get people off the field after being penalized for an illegal formation due to personnel confusion between the offense and the punt team. But as video of the incident on the internet went viral, Tuberville apologized to Oliver on Sunday and publicly on Monday. He was reprimanded by the Big 12 Conference, but Tech has not announced any further action.

■ Dec. 2, 2012: After finishing the season 7-5, Texas Tech accepts a bid to face Minnesota in the Meineke Car Care Bowl of Texas at Reliant Stadium in Houston. It would have been the second bowl appearance for a Tech team in three seasons under Tuberville. Alas ...

■ Dec. 8, 2012: Tuberville shocks the college football world by resigning as head coach of Texas Tech to become the head coach at Cincinnati, a process that began with a phone call around 9 a.m. Saturday morning and ended with Tuberville’s resignation two hours later. Hocutt expressed surprise, saying Tuberville “looked me in the eye and gave me his commitment and dedication to Texas Tech football” just the day before.
